Please provide values below to convert Electron radius (classical) [r_e] to Earth's polar radius [R_p], or Convert Earth's polar radius to Electron radius (classical).
How to Convert Electron Radius (Classical) to Earth's Polar Radius
1 r_e = 4.43298746468381e-22 R_p
Example: convert 15 r_e to R_p:
15 r_e = 15 × 4.43298746468381e-22 R_p = 6.64948119702572e-21 R_p

Electron Radius (Classical)
The classical electron radius is a quantity with the dimension of length, approximately 2.82 x 10⁻¹⁵ meters.
History/Origin
The classical electron radius is a concept from classical physics that attempts to model the electron as a spherical shell of charge. It is not considered the actual size of an electron.
Current Use
The classical electron radius appears in the Thomson scattering cross-section and is a useful length scale in atomic and high-energy physics.
Earth's Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
